Playback and rendering very slow on new Ryzen 7 1700 build

Hello everyone,

I hope someone can help me with the issues I've been having.
Recently I build myself a new rig with these specifications:

CPU: Ryzen 1700 (no overclock present)
GPU: Asus Strix RX 470 4GB

RAM: 2 x 8GB Corsair DDR4 Vengeance LPX @2666Mhz
Mobo: Asus Prime X370-Pro
SSD: Samsung 960 256GB <--- Where I edit my footage from

Latest Adobe Premiere Pro CC build is installed

I made a new project (about 1 minute length) with test footage in the .R3D format, and tried to export that footage with some color correction applied and some basic video transitions in between. The playback was pretty awful and would stop half way most of the time. I was using GPU acceleration (openCL) the entire time and the playback was choppy at best. The real problem started to happen when I tried exporting this project using the media encoder program. Encoding this 1 minute timeline took a whopping 45 minutes using openCL, whereas my older intel build with these speccs;

CPU: i7 4790k
GPU: intel HD4600 (integrated)

RAM: 4 x4GB
Mobo: MSI z97 Gaming 5
SSD: (Same as the above)

Latest Adobe PremierePro CC build is also installed

would do it in 25 seconds, give or take. This was also using OpenCl. I have been running a hardware monitor when I started playback or encoding and it would show me 100% GPU usage all the time with a few percentage dips here and there. The strange thing is that when I use the 'software only rendering' option I have no problems at all. It's slower(1 minute and 25seconds) compared to what GPU accelaration should be in this case as far as I know, but it works.

Most of my projects require me to have as little rendering time as possible, so what am I doing wrong here?
Is this a driver issue from AMD's side or something different? Any help would be apppreciated!

    Correct answer DflippinK

    Is the RED footage 4K or greater resolution?

    Turn off OpenCL rendering and use software. The RX470 is way too slow for serious rendering. That's why the Intel system is faster, becuase it's NOT using OpenCL.

    I have a RX580 with 8GB or Ram, and it is just okay when dealing with 4K H.264. It's much better working with DNxHR/ProRes footage.


    1. id say lose the amd cards for now.. aim to replace it with something along the lines of a gtx 1070... 1080 if you can afford one... EVGA has alot of great options for those cards.. you could try a 1060, but i think you will be happy with the upper end of the spectrum.

    2. you need to absolutely run either the "High Performance" or "Ryzen Balanced" power profile in Windows..

    3. Make absolutely sure you disable the HPET for good...

    Then open up command prompt as an administrator and execute..

    C:\Windows\system32>bcdedit /deletevalue useplatformclock

    it will either tell you that the element was not found, meaning it is already off, or it will complete successfully and shut off HPET.. either way, after that, reboot.

    4. you should be handling premier nicely at this point... the most drastic difference will be from the gpu... but the others are also critical..

    you also can at this point bump your cpu frequency up a little bit as the stock speeds on the 1700 are pretty low... id probably shoot for around 3.6ghz on your chip as it is plenty fast and running more than comfortable.. and premiere should fly...

    Let me know if you need any help..

    Hey I have the same issue but with a rx470 and the only thing that work for me is killing the asus aura gpu process in the task manager and disable the steam home stream so I can use the opengl without dropping frames in the timeline.

    Thanks for your detective work.  Just another couple of programs that interfere with video editing.  Every new computer must be tuned to get rid of these type CPU/GPU stealing performance programs and processes.  My editing only windows 10 computer at startup is as seen below, this is extreme while my Internet cruising laptop has 70 processes   :

    What are your render times like now with the 1070 and the overclock? I just built a 1700X system and I'm waiting for the price of the AMD RX Vega to drop to something sane.

    My render times are pretty good actually! I just finished a larger project, with mostly 4K H.264 footage, color correction applied etc. I rendered the eight episodes of the project (+/- 20 minutes of footage per episode) to 1080p H.264 in about 14 minutes per episode give or take.

    I'm very pleased about my build in general, I have been from the beginning.
    In my opinion Ryzen is one of the greatest things to happen to the CPU market in years.

    Test you new system with my Premiere Pro BenchMark (PPBM) and let us see how it works with this Premiere Pro test tool.  The H.264 timeline has some 4K R3D media in it.

    as estarkey points out, its possible the rx 470 is overloaded with red media vs the 8 cores on the ryzen cpu. whats the cpu usage % when exporting on the ryzen system, with opencl and with software only? when you do opencl whats the gpu usage %? you can use gpu-z  to see it (gpu load %).

    some other considerations, do you have the ram running at 2666?  you could probably also overclock the ryzen cpu to 3.4-3.6ghz, or slightly higher if you have a decent cooler, if you want slightly better performance.

      First of all a big thank you for your response Jim, though I must admit I'm a bit dissapointed that apparently AMD hardware is not being supported as much as Intel/Nvidia or at least that's what I conclude from what you posted in the article (correct me if I'm wrong).  I build this PC almost exclusive for editing purposes, and after seeing some great and positive reviews for the new ryzen platform I made my choice to switch from Intel to AMD. I'm considering returning my RX 470 and switching back to Nvidia after reading this. In any case thank you again for your response
